Overview of Mail Function Section 8-1
ON, the mail transmission is started according to the mail settings that have
previously been made in the CPU Bus Unit System Setup.
If a transmission is restarted while the mail processing is still in progress, it
will be invalid. After the transmission has been completed, the Ethernet Unit
will automatically turn the switch OFF again. Once the switch has been turned
OFF, another mail message can be sent.
Unit Control Switches: CIO 1500 + (25 x unit number)
Triggered by Error Log
Recording
If there is a need for immediate notification when an error occurs, e-mail can
be sent at the same time as an error is recorded in the error log. When an
error to be recorded in the error log occurs, the e-mail transmission is started
according to the mail settings that have previously been made in the CPU Bus
Unit System Setup.
Note If several errors in a row are recorded in the error log, the notification of these
errors may all be included in the same e-mail message.
Triggered at Regular
Intervals
If there is a need to periodically check the Ethernet Unit’s status, e-mail can
be sent at regular intervals. With this method, e-mail is sent at fixed time inter-
vals according to the mail interval and mail information settings in the CPU
Bus Unit System Setup.
Note After the mail processing has been completed, the next e-mail will be sent
when the fixed time interval elapses. There may be discrepancies in the trans-
mission intervals if the Ethernet Unit status causes the processing to take
more time.
8-1-4 Mail Status
The mail status is reflected in the Mail Status areas in the CPU Bus Unit
words allocated in the DM Area. It can be checked as required.
